Hebrews 10
26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
erm... really? These people were believers being told that if they were to sin wilfully there would be no more sacrifice for sins.
23 Let us hold fast the profession of our faith without wavering; (for he is faithful that promised
24 And let us consider one another to provoke unto love and to good works:
25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
28 He that despised Moses' law died without mercy under two or three witnesses:
29 Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
Maybe the let us hold fast to the profession of our Faith helps identify them as believers.
These are to provoke each other unto good works...
It does not say if you unbelieve there is no more sacrifice it states if you sin willfully.
He 10:26 IMO is not addressed to believers; but rather to the Tares.
